We present new transit light curves for planets in six extrasolar planetary\nsystems. They were acquired with 0.4-2.2 m telescopes located in west Asia,\nEurope, and South America. When combined with literature data, they allowed us\nto redetermine system parameters in a homogeneous way. Our results for\nindividual systems are in agreement with values reported in previous studies.\nWe refined transit ephemerides and reduced uncertainties of orbital periods by\na factor between 2 and 7. No sign of any variations in transit times was\ndetected for the planets studied.\n
